摘  要

 自然界中的大多數(shù)景物的外形是隨機(jī)變化的，如云彩、爆炸、浪花、雨和雪等，很難用常規(guī)的建模方法及模擬技術(shù)來描述。因此自然景物的模擬一直以來都是計(jì)算機(jī)圖形學(xué)領(lǐng)域研究的熱點(diǎn)和難點(diǎn)。就爆炸模擬而言，因其形狀與性質(zhì)在時(shí)間上和空間上的多變性，而更具有挑戰(zhàn)性。
 本論文選擇爆炸作為模擬的對象，首先分析了粒子產(chǎn)生效果的原理以及介紹基于3dmax軟件中的粒子系統(tǒng)制作的過程。然后，分析了爆炸的整個(gè)過程和外觀特征，初始化新的爆炸粒子的位置屬性以及新的粒子產(chǎn)生的位置屬性。在整個(gè)過程加入重力，風(fēng)力和阻力以模擬真實(shí)場景效果。在畢業(yè)設(shè)計(jì)中完成了爆炸效果以及對此效果進(jìn)行優(yōu)化。最后論文對粒子系統(tǒng)制作特效過程進(jìn)行了總結(jié)，以及粒子系統(tǒng)在未來各個(gè)領(lǐng)域的展望。

ABSTRACT

Most features of the natural world in the form of random changes, such as: clouds, explosions, spray, rain and snow, and so on, it is difficult to use conventional method of modeling and simulation techniques to describe. Therefore  the simulated computer graphics of the nature has been a hot and difficult area of research . On the simulated explosion, because of their shape and nature in terms of time and space on the variability, and more challenging.
Papers chosen the simulated explosion as the object. First, analysising the effect of particulates on the principle and based on 3dmax particulates in the system software produced by the process. Then, the particle system in accordance with the principles of particle effect of the explosion of the whole process and appearance characteristics, the initial explosion of new particles and the location of the new particle attribute the location attribute. Dynamically change the movement of explosive particles, And give full consideration to the authenticity of the explosion, in the process by adding gravity, wind and obstacles to simulate the real scene effect. Finally, Papers will be conclude for the particle system effects production process : that the general law and the particle system in the future prospects in various fields.
